I'm quite new in town .   Well , do you know where the post office is ?   No , I don't . But I do know where the shopping mall is .   That won't help us . Let me see now ... Why don't you follow this street , Elm , until , you get to the second stoplight .   Well , thank you very much , I hope I can find it .
